Eplerenone as a novel treatment for persistent subretinal fluid following retinal detachment surgery

PURPOSE: To describe the clinical course of a patient with persistent subretinal fluid (SRF) after primary scleral buckle surgery for a rhegmatogenous retinal detachment (RRD) repair who was subsequently treated with oral eplerenone for resolution of SRF. OBSERVATIONS: A 34 year-old-male presented with a large bullous macula-involving RRD of unknown duration and underwent primary scleral buckle and retinotomy for drainage of subretinal fluid (SRF). His post-operative course was characterized by persistent macular SRF for 1.5 years with poor vision largely unchanged from his pre-operative presentation. Patient declined additional surgical treatment and opted for conservative management. Given such persistent SRF, the patient was trialed on a course of oral eplerenone 50 mg po bid. After only one month on this therapy, a marked decline in SRF was noted with near complete resolution after two months. CONCLUSIONS AND IMPORTANCE: To our knowledge, this is the first report of its kind to show the effectivity of oral eplerenone treatment in the reduction of SRF following retinal detachment surgery.
